Construction costs are currently skyrocketing

What about Japan? Much cleaner and no one gets whipped?

I think the Japanese basically have a different mentality. The social environment educates there. But I don't want that here any more than I want Singaporean measures.

Wrong. It’s a question of mentality. There are simply many pig-hedgehogs here who dirty everything. Throwing trash on the street, leaving barbecue leftovers on the beach, graffiti, peeing in the train station, and so on and so forth.
You don’t see this to such an extent in Singapore.
If everyone made an effort, there wouldn’t be so much garbage and dirt to clean up.

I also don’t approve of all the misbehavior you describe.
The question is how far one is willing to go to enforce more “virtuous” behavior?
Singapore’s answer is quite clear: gladly with violence.
And if not immediately, e.g. due to homosexuality or the smallest amounts of narcotics (-> death penalty threatened), then through absurdly high fines, which for a large part of the population, who cannot pay them, leads to harsher, often physical, punishments.
For one undeclared cigarette in your luggage (aka tax evasion) they will nicely rub your face.

But yes, everything is nice and clean there.

Is it worth it?

Always just cherry-picking the best parts is easy. Welcome to Utopia.

It would be much better if school meals or daycare catering were free. But instead, we prefer to promote electric cars that most people with small children often cannot afford.

Wrong, we need both. The world is not just black or white, 1 or 0.

In Bavaria, there is family money for the first 36 months. That is 300 euros per month to support families. Regardless of whether this can stretch parental allowance to 24 months or cover care costs.
In addition, there is a subsidy of 100 euros per month from the first year of life until starting school.

You forgot to mention that these bonuses only exist if you do not send your child to daycare. Rightly, this benefit is therefore called a “stove-top premium.” The opposition wanted to rather invest the money in promoting daycares.

In poor NRW, the view is rather that daycare attendance is valuable for the child, so by now the last and second-to-last kindergarten year is completely free (possibly plus meal fees, depending on the municipality). There are parties here that suggest in their election programs whether the last kindergarten year should even be mandatory to ensure a good transition to primary school (educational level, group behavior, socialization, …).

This nation is culturally that far apart.

That is something said by someone who shared parental leave with his wife and where both parents now only work 70%

How did you divide the parental leave among yourselves? We are also considering that I will take the main part of the parental leave with the next child and then possibly reduce my working hours. Looking forward to an exchange - gladly also via PM.

The problem is that hardly anyone in the Western world has understood how important it is to have more children in order to maintain our prosperity. As has often been written, the aging of our society (and declining birth rates) brings significant disadvantages: less consumption, no economic growth, no money for pensions.

Therefore, it would be wise if childcare were free. In Hungary, once you have 3 children, you no longer pay income tax. Orban has understood this, even if they don't manage it for other reasons.

Living in apartment blocks and multi-family houses then delivers the final blow. In the past, in the countryside, children helped with work and brought in money; in the city, they only cost more money.

... Orban got it ...

I'm brutally ripping this out of context, because, no matter the context, you can't be serious about that?

I'm brutally ripping this out of context, because, no matter the context, you can't be serious about that, can you?

You can find someone stupid and still recognize that they have some good ideas... But yes, definitely somewhat awkwardly phrased... (still... the note that there are problems comes directly in the very same sentence, so did you really have to rip it out of context like that?)
